Leaving school, Valentina and her friend meet up with a certain Samuel who has a little present for Valentina. Imma and Calogiuri see Stacchio's friends and ask them some questions, with the pretext that Calogiuri had lost his dog.

Imma manages to interview Stacchio's father, who is not exactly forthcoming. Back home, Imma gets complaints about her cooking and they listen to the news report about the missing boy.

As sometimes happens, something Pietro says, even in an intimate moment, reminds Imma of some detail in the case. Off she goes with Calogiuri to try for some new leads.

While chatting with her mother, Imma discovers who Peppino Pez Pez was. Diana has the prints from the plates found in Stella's cave dwelling.

Imma and Calogiuri confront De Nardis with the prints from the photographic plates. He admitted to knowing about them, but that was all. While they are there, Calogiuri receives a phone call that might provide some leads as to the red Panda.

Imma and Calogiuri enter the cave where the footing is uneven and the two are thrown together. The police have found the boy and De Nardis is called into headquarters for more questioning.

De Nardis ends up confessing to how things went. He is held responsible for both Stella's and Eustacchio's deaths. Imma is still perplexed, however.

Imma calls the beautician to the Prosecutor's Office, where she asks her some seemingly bizarre questions. Back home, Eustacchio's funeral is on TV. Imma's mind continues to focus on the events surrounding his death.

Imma clears up some more questions with Eufemia Abate about the person Stella was smiling at in the photograph.She has that person summoned for some questioning.

With Francesco Calenzano, whose nickname is Franco, Imma reminisces, in a friendly way, about the summers when they were younger and about the music they would listen to, notably, E ti vengo a cercare (I'll come looking for you).

Calenzano felt the need to tell Imma and Calogiuri some details about his childhood in Switzerland so that they would be able to understand what had happened between him and Stella.

In front of Imma, Calogiuri, and Diana, Calenzano describes every detail of when he went to Stella's apartment to see her. He's distraught, as he relives the experience.

Calenzano finishes telling his story and Calogiuri takes him away. Stacchio's teacher stops by Imma's office with a pupil, Nicolas, who has a story of his own to tell.

Pietro goes to his saxophone teacher's house to help her with a technical problem. At home, Imma gets an important phone call that has nothing to do with the case she just solved.
